Abstract

   The RTFM Traffic Measurement Architecture provides a general
   framework for describing and measuring network traffic flows.  Flows
   are defined in terms of their Address Attribute values and measured
   by a 'Traffic Meter'.

   This document defines a Management Information Base (MIB) for use in
   controlling an RTFM Traffic Meter, in particular for specifying the
   flows to be measured.  It also provides an efficient mechanism for
   retrieving flow data from the meter using SNMP. Security issues
   concerning the operation of traffic meters are summarised.
